A signal generator which will provide_an accu-
rately calibrated signal at the frequencies listed.

An output meter.

Dummy antenna: .1 mfd. _ RMA loop.

Dial chhalism

The following equipment is necessary to properly align this chassis:

Intermediate Frequency and Oscillator adjustmInts
may be made with the loop disconnected provided o
resistor of 10,000 to 50,000 ohms is substituted to
close the lZSK'lGT grid circuit. The loop alignment
must he done with the loop and chassis mounted in
operating position in the cabinet. A single turn loosely
coupled to loop may be substituted for RMA loop,
